Abstract

House dust mite is closely associated with the incidence of allergies such as asthma, atopic dermatitis and allergic rhinitis. Spesies of house dust mite which has been proven to be related with the incidence of allergies are Dermatophagoides pteronyssinus and Dermatophagoides farinae. The purpose of this study is to describe the density of house dust mites species  in residence houses in Kelurahan Jati. The study was a descriptive study with 96 samples taken from  two habitats, namely beds and carpets in 48 homes that have been selected randomly. House dust mites were identified using a light microscope with magnification of 40 times. The results showed that 56 of 96 samples were positive of house dust mites. This study showed that Dermatophagoides pteronyssinus was the most commonly found spesies of house dust mite (71 mites) with the highest density in the bed (6.88 mites/ gram of dust). Species Dermatophagoides farinae only found as many as 5 mites with the highest density in the carpet (0.46 mites/ gram of dust). The conclusion of this research is the density of house dust mites in Kelurahan Jati are quite low so that the possibility to cause allergic diseases is very small.

Abstract

Dissolved organic matter (DOM), which is part of of natural organic matter or NOM, contained of carbon compound and can cause problems related to taste, odor, and disinfection by-products (DBPs) in water and treated water. Permanganate is strong oxidant and have been know its efficiency in oxidazing organic compound. Coagulation is most widely used in all water treatment plant due to its efficiency in removing suspended solid. The objectives of this study is to characterize and to remove natural organic matter in term of  DOM  in water through KMnO4 preoxidation, Al2(SO4)3 or FeCl3 coagulation, KMnO4 preoxidation followed by Al2(SO4)3 or FeCl3 coagulation. Raw water, which was taken from Jagir River in Surabaya, and treated water were measured quantitatively by using total organic carbon (TOC), ultraviolet at wavelength 254 nm (UV254) in order to know its aromatic properties. In addition, fourier transfor m infrared spectroscopy (FTIR) was used to identify the functional group of DOM in water and treated water. The results showed that raw water has high TOC concentration (6,9 mg/L) and mainly composed of aromatic (UV254 0.075 cm-1). The optimum result showed that TOC concentration and UV254 removed significantly into 4,2 mg/L and 0,0020 cm-1, respectively after preoxidation followed by FeCl3 coagulation. According to FTIR analysis, mostly single bond carbon such as C-O and C-H still exist in treated water. This results indicated that preoxidation-coagulation has a better performance than preoxidation only and coagulation only.

Abstract

Biogas adalah gas yang dihasilkan melalui proses anaerobik bahan organik dalam digester atau bak penampung menjadi energi. Energi yang dihasilkan dapat digunakan sebagai pengganti minyak tanah atau gas elpiji untuk memenuhi kebutuhan sehari-hari seperti memasak. Nagari Aie Tajun merupakan daerah dengan mayoritas bermata pencaharian petani dan peternak. Para peternak memiliki sapi setidaknya 3-4 ekor sapi, tapi hampir tidak ada yang memanfaatkan kotoran sapi sebagai sumber energi melainkan hanya dibuang begitu saja. Tujuan penelitian ini adalah untuk untuk mengatasi masalah kotoran sapi yang belum digunakan oleh petani sebagai biogas. Penelitian dilakukan dalam beberapa tahapan, meliputi pembuatan instalasi biogas, uji teknis terhadap biogas dan pendampingan terhadap masyarakat. Berdasarkan hasil penelitian didapatkan bahwa gas sudah mulai terbentuk pada hari ke 15 dan maksimum pada hari ke 21 dengan ditandai dengan menggelembungnya digester dan keluarnya bau khas kotoran sapi. Pengisian kotoran sapi ke dalam digester perlu dilakukan minimal setiap dua sampai tiga hari sekali dengan kotoran sapi sebanyak 20 - 30 liter. Biogas yang dihasilkan telah dapat dimanfaatkan untuk memasak sehari-hari oleh masyarakat setempat.

Abstract

The objective of this study was to analyze the concentration of PM2.5, CO and CO2 indoor due to the use of biomass stoves and to calculate the value of combustion efficiency and fuel use efficiency in biomass stoves. The test was conducted by the water boiling test method to simulate the cooking process that was divided into 3 phases. The fuel used was coconut shell briquettes and firewood briquettes. Based on the test results the obtained concentration of PM2.5 from the the use of coconut shell briquette was 21.03 µg/Nm3 during the cold start phase, 23.66 µg/Nm3 in the hot start phase, and 15.57 µg/Nm3 in the simmering phase. As for Firewood briquette, it had lower PM2.5 concentrations, i.e., 17.17 µg/Nm3 in the cold start phase, 20.63 µg/Nm3 in the hot start phase, and 12.17 µg/Nm3 in the simmering phase. The results of CO concentration measurement in coconut shell briquette for the cold start, hot start, and simmering phases were 4.57; 4.32 and 5.27 ppm, respectively, and for firewood briquette were 3.92; 3.69 and 4.61 ppm, correspondingly. While for CO2 concentration measurements, for coconut shell briquette at cold start, hot start, and simmering phases were 376.83; 364.56 and 443.11 ppm, respectively, and for firewood briquette were 397.4; 383.61 and 486.45 ppm, accordingly. The concentration of PM2.5, CO and CO2 did not exceed the indoor air quality standard regulated by the Minister of Health Regulation No. 1077 of 2011 which is 35 µg/Nm3 for PM2.5, 9 ppm for CO and 1,000 ppm for CO2. The ratio of the biomass stove CO / CO2 briquette fuel was below the value of 0.02 which means that the combustion process occurred perfectly. The efficiency value of coconut shell briquette combustion was lower than that of firewood briquette combustion which is influenced by heating value, water temperature, the amount of fuel used and the length of the testing process, while the efficient use of fuel from using briquettes was better than biomass stoves made from unprocessed/raw biomass fuels.

Abstract

Risk management is a process of knowing, analyzing, and controlling risks of every activity in product and, service sectors. The aims are the process runs effectively and efficiently. One of the ISO studies on risk management has been guided in ISO 31000. This ISO provides a standard framework with the title "Risk Management-Principles and Guidelines on Implementation". Based on the sources in the Ministry of Health in 2016, there are 2,488 hospitals spread throughout Indonesia. However, only 10.29% of hospitals have ability to control the Wastewater Treatment Plant (WWTP) properly. The purposes of this research are determining risk priority of Wastewater Treatment Installation and prioritizing risk evaluation of WWTP at Ibnu Sina hospital, Padang. In this research, fuzzy AHP method was used. The questionnaire was validated by environmental department which monitors hospitals’ waste. After ranking the priority risk, Risk Breakdown Structure method was then being used to evaluate the risk that has potentiallty in waste water processing.The result from the fuzzy AHP are five risks, the main priority risk is the pipe with sub risk of liquid waste stuck with value of 0,0779.  The second risk is septictank with excess nitrification sub risk with value of 0,0713. The third risk is the sampit with subcritical liquid waste spilled with value of 0,0642. The fourth risk is the lack quality of human resources with the weight value of 0,0590 and the fifth risk is the blower with the condition is not feasible to use with the weight value of 0,0548.

Abstract

The City of Jambi has three entering gateways for people from other places to get in using arterial roads. Two roads link Jambi City with South Sumatera, West Sumatera and also Riau Provinces, and one another connects to West Tanjung Jabung and East Tanjung Jabung Regencies. Many vehicles, starting from individual cars and motor cyclesuntil HDV with more dimensions such as trailer truck, have increased air pollution and would generate effect to human health. The research aimed to estimate the load emission from mobile sources on those gateways using Mobilev 3.0 software, and converted the results using Microsoft Excel for advance analysis. Data input came from the number of vehicles from General Sudirman Street, West Ring Road, Surya Dharma Street, South Ring Road, East Ring Road, and Yos Sudarso Street which was enumerated by direct observation using traffic counting method. The results showed that the highest emission (ton/year) to CO and HC was from General Sudirman Street and for CO2, NOx, PM10, and soot was from South Ring Road. The total average daily traffic (ADT) was 435,684.30 units of vehicles per 24 hours, which the biggest was in General Sudirman Street with 114,451.30 units of vehicles per 24 hours. Through this research, both the emission load and also the traffic load situation in each road could be described and became the important information on road transportation management related to ambient air pollution and greenhouse gases controlling.

Abstract

Environmental education in developed countries is currently being intensively developed to increase the environmental awareness of the community in order to achieve sustainable development. But for developing countries like Indonesia, is environmental education the most urgent thing to do first to improve the successful implementation of environmental management system? This paper presents an analysis of social aspects related to the environmental behavior of a society, which is about the importance of the "environmental education" factor for people in developing countries in general, in Indonesia specifically. In addition, other factors that form the environmental behavior of the community and their relationships with one another are also discussed. The topic chosen to represent environmental behavior in this paper is the community's environmental awareness for the waste management system in Padang, West Sumatra, Indonesia. This study uses structural equation modeling (SEM) (which consists of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA)) to investigate the environmental behavior of the community represented by 609 respondents living in the Padang city. The results of the study show that environmental education factor is ranked 3rd out of 8 determinants of the formation of environmental behavior in society, namely after the factors of "government role" and "law enforcement". This research is expected to be able to provide information to various stakeholders where providing environmental education to the community has not been able to effectively change the environmental behavior of the community if the government's role in making a good environmental management system and strong law enforcement have not been carried out.

Abstract

Background: Domestic waste is a side product of human activities in the fullfill of daily needs. Organic waste is the most number of waste produced by the household with 60-70% of quantity. And It increases time to time and becomes a big burden for the goverment to manage. Community participation is very expected in handling It’s organic waste. It is needed an appropriate technology wich is implemented by community easily. The author had ever done action research using a technology in producing organic liquid compost from domestic waste, but It had low performance in producing both liquid compost and slow process. Based on this research result, It is very important to create new inovation to increase the performance of composter unit. So, this research aimed to increase the performance of composter unit in producing organic liquid compost from domestic waste.Method: It was an experimental research using pra-experimental design. One unit of composter which was modified on outlet size was used during the research running. To increase the speed in producing liquid compost, It was modified by increasing consentration and volume of Effective Microorganism 4 (EM4) solusion twice in dosering as stater the process. Observation of the process was done to gain information qualitatively on performance canges of composter unit. The data would be analyzed descriptively to illustrate the process canging  and product over the research running.Result: The resarch result showed that modification on outlet size can increase the operational performance of composter unit. The 0,5 inchi of outlet size can  increase the performance of composter unit in releasing liquid compost. So, It can improve the outlet performance compared to previous research. Consentration 10% and 20 times spray of EM4 solution can increase the speed and voluve of liquid compost produced by composter unit. The production of liquid compost increase rapidly on the second month after the process running. The liquid compost production is harvested every three days periodically. The liquid compost produced is one liter per day in average. Conclusion: This research concluded that modification on both outlet size and consentration  and volume of EM4 as starter can increase the performance of composter unit in producing organic liquid compost.
